Hello Blueberry!!!
Welcome. Good questions to have for sure. I'm gonna repeat what Rosie just told you, so I'll stop before I get going here!
I'm on 2000mg of calcium, 1400mg of vitamin D, 500mg of magnesium, 250mg of vitamin B6, and a multi vitamin. I was just told by my physio that apple cider vinegar capsules are really good for arthritis. I have it in my neck.... With your RA, that might help too.
Like Rosie said, just make sure you get the "okay" from your doctor first before taking anything. Don't want to end up with a bad reaction to something.
Ask all the questions you need to okay!
